Speak to Da Vinci inside the Falador Party Room, and learn that he needs the player to make a sword to complete his painting. He will ask that you make a prop sword out of logs. Use a knife on some normal logs to make it, and give it to him.

He will then require some gold and silver paint for the sword, and asks you to speak to Aggie. Head to Draynor Village and speak to her. For the paint, she will require gold and silver dust, which can be obtained by using a chisel on gold and silver ore, or directly on a gold or silver mining rock. Give both dusts to Aggie to create a vial of gold and silver paint, then return to Da Vinci.

Next, he will require a sapphire for the sword. He requires a special type of sapphire, and asks you to speak to Herquin south of Falador's western bank in the gem shop. Herquin will reveal the gems can be found in a moat directly south of the White Knights' Castle, where ceremonial swords were dumped into the moat for each knight that died.

Next, he will require a green dragon to get the idea for his painting. He will require something small. You will look around the room, and will be prompted with three options to choose from: An imp, the gnome child and the Wise Old Man. Pick the first option. As imps are red, you will need a green dye.

The completed display for Da Vinci to paint.

Speak to the Dunce in the party room, and he will be dyed green. Speak to Da Vinci once more to complete the event!

The Party Room contains an entrance to the basement to the north, resembling the game's Main Menu, and has been converted into a museum of past Old School RuneScape updates. Each gallery contains displays of past updates, with the examine text stating their date of release. You can see this area still in the game if you go to the ladder under the Obelisk of Air in the Edgeville dungeon and look to the west.

Attempting to take a slice of birthday cake with a full inventory results in the player stating "I don't have space for cake. The cake is a lie." This is a reference to the puzzle-platform video game Portal.

The deadman mode display is a reference to a player killing B0aty, a well known streamer, during the 4th Deadman Invitational with a dragon warhammer, a weapon often seen as nonviable in PvP.

Attempting to bank blue gems or paint dyes results in the text, "A magical force prevents you from banking this item!"

When speaking with Da Vinci, he asks "could you do me just one small favour?", to which the player has the option of responding with "NO! It's never just one small favour!". This is a reference to the quest One Small Favour.
